First of all, not all TLC disks have low endurance, there are plenty of TLC disks that have 3+ dwpd ratings (5 years), like the Samsung pm1725a and Intel P4610 (I am sure there are even higher endurance disks than the ones I just found).
With that said, yes the rating for these (pm953) disks isn't terribly high (1.3 DWPD), however it is still more than many consumer grade disks and the stories about people buying disks with no endurance left are few and far between.
So yes, if you buy from a reasonable seller I believe the risk is effectively managed.
